<a href="about.html"><b>ReactOS</b></a>® is a open source <a href="http://en.wikipedia.org/wiki/Operating_system" onclick="window.open(this.href); return false;">operating system</a> based on the design of <strong>Windows® XP/2003</strong>. Written completely from scratch, it aims to support from the hardware level right through to the application level. This is not a <a href="http://en.wikipedia.org/wiki/Linux" onclick="window.open(this.href); return false;">Linux</a> based system, and shares none of the <a href="http://en.wikipedia.org/wiki/Unix" onclick="window.open(this.href); return false;">Unix</a>-architecture.
</p>
<br />
<p>
The main goal of the ReactOS project is to provide an operating system which is <strong>binary compatible with Windows</strong>. This will allow your Windows applications and drivers to run as they would on your Windows system.
